Every three or four years I pick a new subject. It may be Japanese art; it may be economics. Three years of study are by no means enough to master a subject but they are enough to understand it. SO for more than 60 years I have kept studying one subject at a time.
Peter DruckerThere is no reason to believe that the people who staff the managerial and professional positions in our service institutions are any less qualified, any less competent or honest, or any less hard-working than the men who manage businesses.

Peter DruckerInnovation is the specific tool of entrepreneurs, the means by which they exploit change as an opportunity for a different business or a different service. It is capable of being presented as a discipline, capable of being learned, capable of being practiced. Entrepreneurs need to search purposefully for the sources of innovation, the changes and their symptoms that indicate opportunities for successful innovation. And they need to know and to apply the principles of successful innovation.
